In Shangjing, most Ratmen had been killed.
Limbs and tainted blood of the Rat Clan flowed into the underground pipe system, alarming the residents of Shangjing and inciting panic, as the new generation firmly believed Ratmen to be urban legends, until they witnessed them with their own eyes.
Ordered by Lady Honma Noriko, Yanagawa Fumihiko set out to investigate, intending to uncover who was slaughtering the Rat Clan in the underground pipelines.
After a 7-hour search, he arrived at the dimly lit Rat's Nest beneath Shangjing. He increased the brightness of his vision gear only to see the Rat Clan eradicated, with not a single survivor, including thousands of starving refugees who were in the process of transforming into Ratmen, now all murdered.
Yanagawa Fumihiko estimated that roughly 30,000 to 60,000 Ratmen had perished silently beneath Shangjing.
